IGNITING DEVICE.

Application filed August 21, 1913, Serial No. 785,898.

To all whom it may concern:

Be it known that I, FRANK L. VAN DUSEN, a citizen of the United States of America, and a resident of the village of Fort Erie, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Igniting Devices, of which the following is a full, clear, and exact description.

My invention relates generally to igniting devices wherein ignition is produced by the frictional contact of two metals, and has for its principal object to provide a device which may be applied to or made a part of lamp or lantern burners, or the like, for automatically lighting the same.

Another object of my invention has been to provide a device which shall be simple and cheap to manufacture, easy to operate, and one which shall not very readily get out of order.

As is well known, the diameter and pitch of the screw threads on lantern burners are standardized and I have sought to provide an igniting device and lantern burner which is adapted to replace any standard lantern burner without any trouble, inconvenience or fitting on the lantern.

Reference is to be had to the accompan Y4 ing drawings forming a part of this specilication, in which like characters of reference indicate like parts throughout the several views, of which:

Figure 1 is a side elevation of my device with. a portion of the wick raiser stem broken away and shown in section. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view and is taken on line 3-3 of Fig. 1. Fig. 4: is a sectional elevation of my device and is taken on line 1-4: of Fig. 3. Fig. 5 is a fragmentary sectional view taken on line 5 5 of Fig. 2. Fig. 6 is an enlarged fragmentary view showing the friction wheel and a part of the means for operating the same. Fig. 7 is a sectional view of a portion of my device and is taken on line 7-7 of Fig. 3.

In the drawings, 7 represents the burner ofmy device and 8 the casing thereof.

9 is the Wick tube and 10 the Wick raiser stem.

11 are the star wheels, which are provided with central square-shaped apertures and slidably mounted upon the square-shaped wick raiser stem 10 and arranged to project inside of the wick tube 9. These star Specification of Letters Patent.

wheels are arranged in slots provided in a member 12 carried by the casing, whereby movement parallel to the axis of the stem 10 is prevented. Disposed outside of the casing 8 and about the stem 10 is a helical spring 13 which has one end bearing against the casing 8 and the other end against the collar 14, rigidly secured to the stem 10. A tubular casing 15, secured at its inner end to the casing 8, is disposed over the helical spring 13 and collar 1 1, thus protecting the spring against injury and guiding the outer end of the stem 10 as it is moved in and out. The wick raiser stem is provided at its outer end with aknurled disk 16, by which the same may be rotated and moved axially. Carried in the lower part of the casing 8 is an inwardly extending square-shaped tube 17. In this tube is slidably arranged a gear rack .18. This rackis provided with a right-angled inwardly extending arm 19, to the inner end of which is pivotally secured the inner end of the wick raiser stem 10, whereby the rack 18 may be moved back and forth by means of the stem. The inner end of the arm 19 is provided on each of its sides with a groove 20, which engages with longitudinal guide-ways 21 carried by the extension 22 of the casing 8, (see Fig.

7) whereby the rack is guided throughout.

its travel. The rack 18 is in mesh with a spur gear 23, whlch 1s partially rotated when the rack is operated. This gear 1s rotatably carried within a casing 24 and is in mesh with a gear pinion 25, which is rotatably mounted at the lower end of the friction wheel shaft 26. A. ratchet wheel 27 is also rotatably mounted, upon the shaft 26, above and adjacent to the pinion 25 and is secured to the pinion so that it will rotate with the same. The shaft 26 is rotatably carried by the casing parts and has rigidly secured near its lower end a disk 28. This disk is mounted above and adjacent to the ratchet wheel 27, and carried on its under side is a pawl 29, which engages with the teeth on the ratchet wheel 27, and by which engagement the shaft 26 is rotated. At the upper end of the shaft is carried a friction wheel 30, which is pro vided with a serrated or roughened surface.

A piece of pyrophorous metal 31 is pro in a short tube 36. A torch 37 is pivotally carried by the casing and is provided with a cap member 38, which is arranged to enter the opening 35 and to normally close the upper, end of the tube 36. A suitable spring 45 is. provided for keeping the torch normally in the position shown in the drawings. The torch is preferably formed of a piece of wire bent in the form of. a spiral spring and with a tuft of asbestos or noninflammable material secured thereto, which is held normally in contact with the saturated packing 39 carried in the upper part of the casing 8. i The torch37 is provided with a rearwardly extending arm 40, havpoint of the torch.

ing its outer end disposed below the pivotal A bell-crank lever 41 is pivotally carried by the casing 8 and has its upper arm in engagement with the arm of the torch. The lower arm of the bellcrank lever 41 extends downwardly and has its extreme lower end in engagement with the uppersurface of the gear 23. This gear is provided with a raised cam face 42, which, when the gear is rotated, engages with the lower arm of the lever 41 and causes the same to be slightly rotated, thus raising the torch to its'uppermost position. The burner of my device is provided with the usual screwthreaded portion 43, which fits into the oil container 44 0f the lamp or lantern,-shown in dotted lines in Fig. 1.

When my deviceisto be operated the wick raiser stem 10 is rotated so as tobring the upper end of the wick in the position shown in the drawing where it can be easily lighted. The wick, having been turned up, the wick raiser stem 10 is now pushed inwardly against the tension of the spring 13, which causes the rack 18 also to be moved inwardly. As the rack 18 is actuated, the gear 23 will be partially rotated, and as it rotates the raised cam-face 42 will contact with the lower endof the bell crank lever 41, which in turn will push the arm 40 of the torch and raise the same into the ignition field, where it will receive the sparks coming from the friction wheel and pyrophorous metal. The friction wheel 30 carriedby the shaft 26, is operated through the medium of the gear pinion 25, meshing with the gear 23 ,and the ratchet wheel 27, pawl 29 and disk 28. It will be clearly seen from the drawings that when the rack 18 is pushed inwardly, the pinion 25 and attached ratchet wheel 27 will be rotated clockwise, and when the ratchet wheel is traveling in this'direction one of its teeth will engage with the ratchet pawl carried by the disk 28 rigidly mounted on the shaft 26, and causethe rotation of said shaft and friction wheel in a clockwise direction. W hen rotated the friction wheel will discharge a series of sparks into the ignition field and against the torch 37 hen the pressure on the wick raiser stem 10 is released, the spring 13 will carry the same back to its normal position as shown in the drawings. As the stem is moved to its normal position, the rack 18 will also be drawn inwardly and cause a reverse rotation of the gear 23. This will move the cam-face 42 out of engagement with the lower end of the bell crank lever 41, and thus allow the spring 45 of the torch to force the cap member 38 down upon the upper end of the tube 36, and thus lower the torch into the receptacle and close the top of the tube 36. When the parts of the device are moving to their normal positions, the gear pinion, together with the ratchet wheel 27, will be rotated in a counter-clockwise direction, and when rotating in this vdirection the ratchet wheel will be released from its engagement with the pawl 29 and disk 28. Thus, it will be seen, that the shaft 26, friction wheel 30 and disk 28 carried thereby, will be rotated only in one direction and will remain stationary when the parts of the device are moved in the opposite direction, thus throwing the igniting sparks into the ignition field only.

The packing 39 contained in the casing 8 is saturated l with a volatile fluid, such as gasolene or the like, and the torch 35 being in contact with the said packing, it also will be saturated with the volatile fluid. Thus, it will be clearly understood, that when the torch 35 is raised in the position shown in dotted lines in Fig. 5, the sparks coming from the pyrophorous metal will cause the volatile fluid in the torch to be quickly ignited. The torch when ignited, being in a position adjacent to the burner, the wick will be lighted therefrom, whereupon the wick raiser stem 10 and the parts connected thereto are permitted to return to their normal positions.

While I have shown and described my invention as applied to a lantern burner, it is obvious that it may be used with equal efliciency, to ignite lamp burners, gas burners, or the like.
